Question: a solar panel on a geo satellite tracks the sun...

Question details

A solar panel on a GEO satellite tracks the sun; the back of the panel faces dark space (Ispace. ~ 3K). The cells have an energy conversion efficiency of 12%. The effective front-surface solar absorptivity isa0.90, an the infrared emissivity is0.94. The anodized aluminum back surface panel has infrared emissivity 0.80. What is the steady-state operating temperature of the array. Hint: Assume heat flux in qin S equal to got heat flux out from front and back panels. Stefan-Boltzmann constant is σ 5.6704 x 10-8 m2R solar panet Tsun-1400a qback- back Ơ(Tpanel-Tspace) q front-Efrontơ (Tpanel-T pace)
